This randomized controlled trial evaluated the therapeutic benefit of mental practice with motor imagery in stroke patients persistent upper limb weakness. There is evidence to suggest that rehearsal movement can produce effects normally attributed practising actual movements. Imagining hand movements could stimulate restitution and redistribution brain activity, which accompanies recovery function, thus resulting a reduced deficit. Current efficacy for insufficient due methodological...
Objective: To assess the efficacy of motor imagery training for arm function in chronic stroke patients. The relation between mental processes such as attentional and perceived personal control over recovery, was additionally investigated. Design subjects: Twenty patients with long-term impairments (mean two years post stroke), were assessed before after four weeks training. Ten mentally rehearsed movements their affected arm. Their recovery compared who performed nonmotor (n =5), or not...
The perception of object-directed actions performed by either hands or tools recruits regions in left fronto-parietal cortex. Here, using functional MRI (fMRI), we tested whether the common role and object manipulation is also reflected distribution response patterns to these categories visual In two experiments found that static pictures activated closely overlapping lateral occipitotemporal cortex (LOTC). Left LOTC responses selectively overlapped with but not whole bodies, nonhand body...
Accumulating evidence points to a map of visual regions encoding specific categories objects. For example, region in the human extrastriate cortex, body area (EBA), has been implicated processing bodies and parts. Although monkey, neurons selective for hands have reported, humans it is unclear whether areas individual parts such as hand exist. Here, we conducted two functional MRI experiments test hand-preferring responses cortex. We found left lateral occipitotemporal cortex all 14...
Although the adverse consequences of changes in social behavior following traumatic brain injury (TBI) are well documented, relatively little is known about possible underlying neuropsychological deficits. Following a model originally developed for deficits schizophrenia, we investigated whether impairments emotion recognition, understanding other people's intentions ("theory mind"), and cognitive flexibility soon after first TBI or 1 year later were associated with self proxy ratings TBI....
Abstract The distribution of attention between competing processing demands can have dramatic real-world consequences, however little is known about how limited attentional resources are distributed during behaviour. Here we employ mobile EEG to characterise the allocation across multiple sensory-cognitive naturalistic movement. We used a neural marker attention, Event-Related Potential (ERP) P300 effect, show that targets reduced when human participants walk compared they stand still. In...
Importance Exposure to traumatic brain injury (TBI) has raised widespread concern over participation in sports, particularly possible long-term consequences. However, little is known about the outcomes of individuals presenting hospitals with sports-related TBI. Objective To compare characteristics and non–sports-related Design, Setting, Participants The CENTER-TBI (Collaborative European NeuroTrauma Effectiveness Research TBI) observational cohort study was conducted at 18 countries....
Background Most of us are poor at faking actions. Kinematic studies have shown that when pretending to pick up imagined objects (pantomimed actions), we move and shape our hands quite differently from grasping real ones. These differences between pantomimed actions been linked separate brain pathways specialized for different kinds visuomotor guidance. Yet professional magicians regularly use deceive audiences. Methodology Principal Findings In this study, tested whether, despite their...
Line bisection has long been a routine test for unilateral neglect, along with range of tests requiring cancellation, copying or drawing. However, several studies have reported that line bisection, as classically administered, correlates relatively poorly the other to extent some authors questioned its status valid neglect. In this article, we re-examine issue, employing novel method administering and analysing proposed by McIntosh et al. (2005). We report measure attentional bias yielded...
The potential effects of exposure to repetitive subconcussive head impacts through routine participation in sport are not understood. To investigate the we studied boxers following customary training (sparring) using transcranial magnetic stimulation (TMS), decomposition electromyographic (EMG) and tests memory.Twenty amateur performed three 3-min sparring bouts. Parameters brain function motor control were assessed prior again immediately, 1 h 24 post-sparring. Twenty participants...
Abstract The study of cognitive processes underlying natural behaviors implies departing from computerized paradigms and artificial experimental probes. present aims to assess the feasibility capturing neural markers (P300 ERPs) evoked in response identification task-relevant objects embedded a real-world environment. To this end, EEG eye-tracking data were recorded while participants attended stimuli presented on tablet they searched for books library. Initial analyses library revealed that...
Most studies into acquired theory of mind (ToM) deficits assessed patients once, long after the onset brain injury. As a result, time course ToM impairments is largely unknown. The present study examined whether following traumatic injury (TBI) recover, remain stable, or worsen over time. Because alleged association between and social communication, may deteriorate because changes in patients' environment ability executive functioning were shortly at 1-year follow-up. Compared with...
This multiple single case study contrasted left hemisphere stroke patients (N=6) to healthy age-matched control participants (N=15) on their understanding of action (e.g., holding, clenching) and motion verbs (e.g. crumbling, flowing). The tasks required correctly identify the matching verb or associated picture. Dissociations content depending lesion site were expected. As predicted for containing an and/or content, modified t-tests confirmed selective deficits in processing with lesions...
The ability to safely negotiate the world on foot takes humans years develop, reflecting extensive cognitive demands associated with real-time planning and control of walking. Despite importance walking, methodological limitations mean that surprisingly little is known about neural processes support ambulatory motor control. Here, we report mobile EEG data recorded from 32 healthy young adults during real-world obstacle avoidance. Participants walked along a path while stepping over expected...
